If the number of positive values in src exceeds the length of dst, then the memory after dst will be overwritten. For example, running out of memorywill often cause a runtime error. These, particularly, are tricky since they may or may not occur based on what the initial garbage value of the index is when you run the program. have a peek at this web-site
